免耕与秸秆施用使得土壤硝化作用和土壤温、湿度不再具有显著关系（p0.05）。

No-tillage and straw addition made the Gn had no significant correlation with soil temperature or moisture content ( p0.05 ) .

低浓度下，La对土壤硝化作用和磷转化作用均有某些刺激作用，但随着浓度的升高产生抑制作用并不断增强。

La has stimulative effects on soil nitrification and phosphorus transformation at low concentration but has inhibitory effect at high concentration , and the inhibition is strengthened with increasing of La concentration .

结果表明甲霜灵对土壤硝化作用有一定的抑制效应，在试验条件下，每千克土壤含25mg甲霜灵时，在用药后4～8周内都表现出对硝化作用的抑制效应。

The result showed that the nitrification of soil was inhibited by Metalaxyl in a certain degree . It was appeared that Metalaxyl had inhibition on nitrifying capacity with 25 mg a. I / kg soil in 4-8 weeks after the bactericide used .

本文对影响天津市城市污水土地处理系统现场土壤硝化作用的一些因子进行了研究。

Some factors affecting the nitrification in soil of the Tianjin municipal sewage Land-treatment System are evaluated in the present paper .

加锌量在200mg/kg以下时对土壤硝化作用和反硝化作用有促进作用，高于该水平则有抑制作用。

Nitrification and denitrification activities were seemingly increased by the zinc added below 200 mg / kg , but decreased above this added rate .

RP与CK、P处理比较，可以刺激微生物活性和增加土壤反硝化作用；

Microorganism activity at the RP treatments could be simulated and soil denitrification increased , compared with the CK and P treatments .

当DL-1用量为（NH4）2SO4氮量的2.0%时，土壤的硝化作用受到了更强烈的抑制，到培养第90天试验结束，土壤中的NO3&N含量始终维持在较低水平。

When the dosage of DL-1 accounted for 2.0 % of applied N , soil nitrification was strongly inhibited , and soil NO_3 & N content remained at a lower level till to the end ( 90 d ) of incubation .

下层土壤反硝化作用的研究

Study on the denitrification in the subsoil

石灰添加剂能增强除混交林外的其它所有土壤的硝化作用。

Lime application increased nitrification in all the soils except for the Chinese mixed forest soil .

2.1000ppm时，几种除草剂对两种土壤的硝化作用有一定的抑制效果，对氨化作用有不同程度的促进作用。

The results also showed that when the concentration of herbicides in soils was 1000 ppm , soil nitrification rate was inhibited but soil ammonification rate was stimulated in certain levels .

在配施氮肥的条件下，秸秆还田促进了土壤反硝化作用，秸秆还田时夏玉米生育期肥料氮反硝化损失率为1.7%、秸秆不还田时为1.2%。

Straw addition stimulated denitrification greatly when fertilizer nitrogen was applied adequately . Ratio of fertilizer N loss induced by denitrification during the whole period of maize growth was 1.7 % for straw addition treatment and 1.2 % for no straw addition treatment .

不同土壤的反硝化作用活性明显不同.山地暗棕色森林土的CH4吸收作用也主要发生在土壤的上层（0&12cm）。

The uptake of CH4 by dark brown forest soil mainly occurs in upper soil layer ( 0-12cm ) .

从而揭示了内蒙古温带草原土壤以异养硝化作用过程为主产生N2O和N2O排放通量较低的微生物学机理。

Thereby , the N2O emission flux from temperate grassland soils was lower because that the heterotrophic nitrification is key N2O production process in these soils .

农业流域水体沉积物和土壤的反硝化作用是农业氮素去除的重要途径。

The denitrification of sediment and soil are considered as the most important way to remove nitrogen from agricultural watershed .

添加抗生素后，虽然导致铵态氮均有一定增加，但硝态氮含量反而下降，这表明土壤中的硝化作用受到抗生素的明显抑制。

The nitrate concentration decreased although the degradation of antibiotics increased soil ammonium concentration , which suggested that nitrification was significantly inhibited by antibiotics . The dynamics of nitrate concentration reflected the combined positive and negative effects .
